Heart shape rendered in dark textured material.

Monochromatic study depicting heart form delineated through texture variation and shadow modeling. Surface composed of granular dark material with contrasting luminous center cavity. Geometric form exhibits symmetrical bilateral structure with defined edges rendered through tonal gradation. Dimensional depth achieved via light penetration through hollow central aperture. Medium appears tactile, possibly crystalline or mineral aggregate composition. Lighting demonstrates side illumination casting interior surfaces in relative brightness against surrounding dark mass.
